Additions and changes to the Twilio platform
The TwiML <Conference> noun and the Conference Create Participant API have been updated to provide a new
announcement status callback event. This event will be sent to the provided status callback URL when the announcement to a conference or a participant ends normally or fails due to a Twilio-internal error.
This allows developers to be informed when an announcement has completed and additional call processing instructions can be executed, or when an announcement has failed and a retry attempt is needed.
